Title: Innovations of David T Thomas
Introduction
David T Thomas is a notable inventor based in Santa Barbara, CA. He has made significant contributions to the field of radio frequency technology, holding a total of 2 patents. His work focuses on advanced antenna systems that enhance the efficiency and effectiveness of radio frequency energy transmission.
Latest Patents
One of his latest patents is for a parabolic antenna with a horn feed array. This invention features a radio frequency antenna that includes a parabolic reflecting surface and an array of feeds positioned near the focal point. The feeds are designed to provide a specific amplitude and phase distribution to radio frequency signals, ensuring that energy is reflected from the surface and combines at the radiating aperture. This results in an antenna pattern with relatively low sidelobes across a wide frequency range. The design incorporates a waveguide section with conductive members that establish the desired amplitude and phase distribution while handling substantial power levels.
Another significant patent by Thomas is for an antenna with a curved lens and feed probes arranged on a curved surface. This system directs a collimated beam of radio frequency energy over wide scan angles. It consists of multiple antenna elements positioned along a curved path, which produces a directed beam of energy. A radio frequency lens is used to collimate this energy, resulting in a uniform amplitude distribution across the beam wavefront. The innovative arrangement of the antenna elements allows for a more compact lens design, enhancing the overall operating effectiveness of the system.
